Pc to 24" TFT issues

[Skinleech]

I recently built up an old PC to run as a NAS, and as an HD capable PC to hook up to the 24" 1920x1200 screen I have in there.

Up until the other day it was all working fine, but when I switched mid week, I encountered a strange problem.

The PC turns on, and boots up, the monitor sees a connection from the PC as it comes out of standby when the PC is turned on, but I get no picture on the monitor, not even the POST screens or XP loading screens. The PC is definitely fine as I access the shared drives over the network.

The PC is as follows:

Athlon XP 3000
1gb Corsair DDR400 RAM
Asus motherboard (can't remember the model number just now)
512mb ATI AGP 2600XT

The 2600XT is connected via DVI to the 24" Hyundai screen.

Any ideas?

Operating system?

First thought would be a graphics card failure.

XP SP3 - I'd wondered about that - but then it's odd that the minitor still detects a signal surely?

I need to open the case and check connections I guess, and I'll try to swap the dvi port on the back of the card.

I don't have another AGP system to check the card in unfortunately.

Any joy with Safe Mode?

EDIT - can you RDP to the machine and see if there's anything odd going on with the card?

[Skinleech]

As I can even get an image on the screen, I can't get to the point where I can select safe mode - I can't even bring the BIOS up, I get a black screen all the way thorugh.

Funnily enough, RDP was the exact reason I turned the machine on to find the issue, I wanted to set one up.

The output ccts that drive the monitor could be OK - so the monitor is detecting something.

Checking the connections wouldn't do any harm - auxiliary power - and try removing and reseating the card from the slot.

you can remotely enable RDP on the machine so long as you know the ip address and there's no firewall blocking it.

Does that help at all?


If you're getting no output, even a BIOS screen then things aren't looking too promising though.

i've just recently got a problem like this as well! the power led comes on but no picture. its not the dvi cable or graphics card as i've used the same cable on a spare monitor and all is fine.... have you tried doing that? if that works then try accessing the OSD menu on the monitor. when i tried opening the menu the monitor didn't show anything, the backlight is definitely not on, but it does detect when a signal is coming from the gfx card though (powered up and shut down and the power led showed me that)

i've just requested a repair/exchange for my monitor, its really annoying. hope your's isn't in the same situation as mine

I'm going to take a look at all this today/tomorrow - thanks for the replies all.

Will post back when I have some more info. I certainly hope the monitor is not on the way out, it's not that old. The other inputs all seem to work ok.

I had an identical problem on a Dell laptop at work last week. (I know your's isn't a laptop but the principle is the same) The external VGA connector seemed ok because the system recognised that a monitor had been connected but there was no output on the screen. It turned out to be a dry joint on the VGA connector where it mounts to the board.

Well, it's all working now. Looks like it was as simple as a bit of pressure on the DVI cable coming out of the card. Ridiculous.

Thanks to all who replied.
